The is a member of the ADP330x family of precision low dropout anyCAP voltage regulators. It is pin-for-pin and functionally compatible with National's LP2980, but offers performance advantages. The ADP3308 stands out from the conventional LDOs with a novel architecture and an enhanced process. Its patented design requires only 0.47 µF output capacitor for stability. This device is stable with any type of capacitor regardless of its ESR (Equivalent Serial Resistance) value, including ceramic types for space restricted applications. The ADP3308 achieves ± 1.2% accuracy at room temperature and ± 2.2% overall accuracy over temperature, line and load regulations. The dropout voltage of the ADP3308 is only 80 mV (typical) at 50 mA. This device also includes a current limit and a shutdown feature. In shutdown mode, the ground current is reduced to ~1 µA. The ADP3308 operates with a wide input voltage range from 12 V and delivers a load current in excess of 100 mA. The ADP3308 anyCAP LDO offers a wide range of output voltages. For 100 mA version, refer to the ADP3309 data sheet.

*This is a stress rating only; operation beyond these limits can cause the device to be permanently damaged.

Function Regulator Input. Ground Pin. Active Low Shutdown Pin. Connect to ground to disable the regulator output. When shutdown is not used, this pin should be connected to the input pin. Open Collector. Output that goes low to indicate the output is about to go out of regulation or no connect. Output of the Regulator, fixed or 3.6 volts output voltage. Bypass to ground with µF or larger capacitor.

EVAL-ADF4193EBZ1 : Product Description
